My AC used to come out of the front "holes" when i set the AC to Min AC or MAX AC but now when i move the knobs to that position it only comes out of the vents thats i use for defrost. Anyone know what the problem might be did i push a wrong button?

Has to be a loose vacuum hose or vacuum cannister.

I'm not familar with late model Mustangs, so someone else chime in here.

If there is a vacuum canister in the engine compartment it is very easy to knock loose a hose resulting in a dash control problem. The cannister should be about the size of a grapefruit, black, with two hoses going to it.

If you recently installed a stereo or did some work under the dash possibly a hose was knocked loose.

The vacuum 'motors' that actuate the various vents and the dash control itself are very reliable and do not fail often.
